Project history
UK Central Government – SAP SuccessFactors Employee Central migration (SC Cleared)
Large multi-department programme migrating HR data to SAP SuccessFactors EC using Syniti ADM, delivered through successive mock load cycles.
- Owned the Job Info object end to end: the largest and most dependency-heavy Employee Central object on the programme, alongside further employee data objects (email, phone, and related personal data) across two government departments. Built a WebApp dashboard to display Job Info’s error reports with record counts as bar graphs to increase visibility and object awareness by the leadership.
- Delivered Job Info ready for the mock cycles loads, despite dependencies on business sign-off and EC functional design.
- Designed and built Syniti ADM source rules, target mappings, value mappings, and pre- and post-load validation and reconciliation reports in SQL Server.
- Kept load cycles on track by building pragmatic, documented workarounds where requirements were still awaiting sign-off.
- Replaced a slow, mandated file-refresh process with a SQL BULK INSERT approach, cutting source refreshes from days to hours. The workstream adopted it and it was shared with other programme teams.
- Built a PowerShell reconciliation script that consolidated refresh reconciliation into a single output, working inside a locked-down jump-server environment with no spreadsheet tooling.
- Trained the programme's junior consultants in Syniti ADM and SQL
